There is to win from the interpreter – it is only reachable via a function pointer stored in the global variable callback . The pointer is used after the instruction loop finishes:
parse_input tokenises the input and stores each instruction as a struct in a global array insts[128] . execute iterates over insts and dispatches to the appropriate handler based on the first byte (the opcode). The interpreter keeps a register file : isaimini.6
The program reads a user‑supplied string (up to 256 bytes) from , parses it as a sequence of ISA‑mini instructions, executes them, and finally prints either Success! or Failure! . There is to win from the interpreter –
